I don't hate our neighbors... but at my parents' house the woman who leases the house next door once cut down all out trees when we were away on vacation because she said they blocked her view (of what, our house??) and put leaves in her yard. She had never asked us to trim back the trees, they were just down one day, and all the debris left in our yard.
She also came over once for reasons I have now forgotten and screamed at my grandmother (88 and ailing) simply because my father wasn't home to yell at. She never seemed to be able to keep tenants more than a year or two. I went to school with the daughter of her "best friend" -- her mother was the only person who would give her the time of day, apparently, so at least it wasn't just us.
